CULTIVATOR.

Application led June 30,

T0 all lwhom t may concern Be it known that I, DALTON K. lViLsoN, a citizen of the United States'of America, and a resident of Vaterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

My invention relates to improvements in cultivators. The object of my improvements is to furnish 'a selfpropelled device supplied with independently operable gangs of soilworking implements; having means for controlling the direction of travel of the device, and also having means for unitedly manually controlling said gangs of implements and steering the device, the last-mentioned means being also movably associated with lsaid gangs to permit said means to be used in changing the direction of travel of the device without acting upon the gangs.

This object have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved cultivator; Fig. 2 is a top plan view thereof, with part of the frame broken away, and Fig. 3 is a rear elevation thereof.

Similar numerals of reference denote cor responding parts throughout the several views.

My improved cultivator is preferably of a self-propelled type, but the character of my improvements is such that they may be used in the same manner in cultivators or similar machinery, which may not be self-propelled.

The numeral 24 denotes a horizontally disposed hollow rectangular frame having fixed hangers 50 provided with outwardly extending stub axles on which are rotatably mounted the traction-wheels 19. Sprocket-wheels of the spur-tooth type 51 are concentrically mounted on said tractionwvheels by clamping members 52 and carry sprocket-chains 53 which are carried over and driven by sprocket-pinions 54 on a rotatable shaft 55 whose end parts are mounted in raised bearings 7 3 on the side-bars of said frame. The numeral 57 denotes a sprocket-wheel fixed on a differential-gear casing 641 and which houses differential gearing of the internalgear type (not shown), such as is shown in my previous Patent No. 1,651,117.5,January 28, 1913. Said transmission device is loose Specification of Letters latent` Patented Aug. 17, 1920.

1919. Serial No. 307,608.

to rotate with the shaft by the following means:

65 is a sleeve grooved annularly to receive a shifting-fork 66 on a bent arm 67, said sleeve being slidably non-rotatably mounted on said shaft and having a clutch-face, not shown, to engage av mating clutch-face in said housing connected therewith. The arm 67 is one of the members of a bell-crank lever which is pivoted at its angle on a stud 68 on the rear cross-bar of the frame. The outer end of the member 69 of said lever has an eye to receive a hooked end of a rod 70 whose rear endhas a looped-handle 71. Manipulation of the bell crank lever by said handled rod 70 shifts the clutch-sleeve 65 into or out of mesh with the clutch-member, not shown, within the housing 64. A prime mover 61 of the double opposed cylinder type, is mounted on the front part of said frame, and a sprocket pinion 59 is mounted on the end of its power-shaft to carry a sprocketchain 58 which is also carried by the sprocket-wheel 57.

` l have provided means for changing the direction of travel of said wheeled-frame 24. The numeral 17 denotes a flat horizontal rock-bar positioned immediately under said frame to extend rearwardly thereof, and having its front end pivoted at 16 to a crossbar 72 of said frame. The front end of this rock-bar is formed with the forwardly extending raiclesegment 15. The middle part of said rock-bar is mounted and supported in a hanger 18 depending from the frame to swing transversely therein, and the rear part of the rock-bar is offset downwardly and provided with upwardly directed spaced lugs 19 and 2O between which the middle part of a bowed axle 47 is secured by means of a bolt 21, and said bolt has a rearwardly extending stem 22, with a terminal looped handle 23 for a purpose to be described.

Small carrying-wheels 48 are mounted on the depressed ends of the bowed axle il?, rotatably. The numeral 14 denotes a rack- "segment which intermeshes with the racksegment 15 and is pivoted at to a cross bar 13 of said frame. Said rack-segment 1l has a forwardly extending medial prejection 62, and a helical tension spring is connected between said projection and the front cross-bar of Said frame, and acts te normally retain said rack-segments and rech-bar in en said shaft but may be engaged therewith the medial longitudinal line ef said frame. 11u

Arms 11 extend integrally and transversely oppositely from the rack-segment 14. The numeral 7 denotes a pair of spaced longitudinally disposed controller-bars positioned immediately below the frame 24 to extend rearwardly therefrom, and are located on opposite sides of the rock-bar 17. The front ends of said controller-bars are movably coupled to the ends of the rack-segment arms l1 by the pivoted connections 8 9, to permit free swinging .movements of the controllerbars. The rear extremities of the controllerbars have clutch-disks 6 radially grooved or dentated to mate with similar clutch-disks 5 on the front endsof arms 2, and said clutchdisks are adjustably secured together by bolts 3 and wing-nuts 4. The rear ends of the adjustable arms 2 are supplied with the looped handles 1.

A bar 26 is iixedly secured along the under face of the front cross-har of the frame 24 by bolts 25, and has at each end dependinghangeis 32 with outwardly turned portions to which are pivotally secured on vertical pivots to swinghorizontally hangerparts 33 having integral flanged members 27 supplied with a vertical row of boltholes 31. A pair of longitudinally disposed .bars 30 have front terminal forks 29 mounted to swing vertically on the plate 27 by means of bolts 28. These pivoted connections render the forward ends of the gangbars freely movable relative to the hangers 32. The rear ends of the gang-bars 30 are swingiiigly connected to the rear part of the main frame 24 by the following means:

The numeral 43 denotes tubular standai'ds whose upper ends are traversed by eyebolts 44. Looped'shaped links 45 are linked to said eye-bolts and the outtiirned extremities are pivoted in staples 46 fixed on said frame. Each standard 43 is ixedly oonnected by means of side-plates 41 to alined standard members 40 below and spaced therefrom, the lower ends of the latter being connected to the rear ends of the gangbars 30 'by movable joints 39. Within the interspace of the side-plates 41 are mounted a pair of vertically-spaced anti-friction rollers 42 and the controller-bars 7 are passed slidably between said anti-friction rollers. On the rear ends ofthe gang-bars 30 are fixed hangers 34 having sleeves 35 in which are mounted the tubular supports 36, the latter oriiiced to receive the Shanks 37 of shovels 38.

Ars shown in said Fig.

ll, the gang-bars 3() are independently controlled, and the frame 24, with its carrying-wheels 49, move to change the direction of travel by inanual actuation of the controller-bars or de-v vices 2-7 alone. To change the direction of travel of the device, the operator shifts the controller-bars 7 longitudinally oppositely, said bars sliding between the sideplates 41 of the standards 40-43 without acting to shift the gang-bars laterally. These movements of the controller-bars rock said rack-segments 14 and 15` appropriately to rock the rock-bar 17 in a desired direction, and as the rear end of the rock-har is connected to the middle of the bowed axle 47, the latter, with its carrying-wheels 48 serve as fulcruming-means so that the frame 24 and its carrying-wheels 49, are rocked relative to said rock-bar on the pivot or king-bolt 16 to change their direction of travel.

Either controller-device 2-7 may be used independently of the other by moving it transversely to and fro to swing its connected gang-bar 30 transversely. or lifted or depressed to raise and lower the gang-bar with its soil-working tools 38. This operation of either or both of the gang-bars, by means of said controller devices, may be effected while the controller-devices are being shifted slidably longitudinally to change the direction of travel of the device.

The handle 23 may be used in lifting the wheels 48 off the ground in swinging the device a half turnin reversing the direction of travel.

Various modifications may be effected in the elements of the device and their arrangementsand yet be covered by the scope of the invention.
